As a indicative timetable :
1-10 days awaiting ship
10-17 days on ship
3-9 days to dealer
I would allow 4 weeks, use marine tracker to follow the ship, some call at Setubal (near Lisbon), where factory that makes Alhambra (and other VW group cars is), discharge at Sheerness, Grimsby, Tyne (pick nearest to your dealer). So further north you are, ship voyage is longer
